As shown on. the I The device o1 this invention is adopted to be secured to on eyeliner-y headlight eesing l which is provld o with source of illuminotion et 2 ordinarily coincldent with the axis thereof. A lens 3 having; e frosted or translucent upper half secured in the front of said casing l in the manner by s rim 5, end supportedin the casing l and surrounding the source of light 2 is nefiector 6, the uppee portion of which extends outwardly and is curved downwardly until the some contacts the lens 8 along a line coinciding with the bottom of the translucentportion 4 thereof The lower portion of the reflector 6 extends around the source of light '2, 0rd? noisily an incandescent electric light bulb, and converges tovvsrds the axis of the casing to s point 7 and from said point 126- flector is provided With plural ty steps or ridges 8 which extend. downwardly in the casing to the lower of the lens 3;

' in the device shown in Figures 8-and 1-, the casing 11 of the headlight is provided with a source of illumination 12 which is surrounded by a reflector 3 adapted to direct the main or bright beam of light outwardly from the headlight through a lens 14:. Said lens 1d is supported in or is integral with a casing 15 which is adj ustably mounted iii-the rim of the headlight on an extension rim 16", and which is preferably constructed of translucent material. The upper portion oil said casing 15 curves downwardly and outwardly to a point 17 slightly below the axis of the casing 11 and at saidpoint 17 said casing 15 is provided with walls 18 extending inwardly forming a lunnel opening through which the main beam of light is projected from the lens 14.

In this style of the invention, the bright part of the beam of light is limited by the edge 17 of the forward portion of the casing 15 and by the'rear edge otthis casing which is found at the bottom of the lens 14. These two edges comprise the defining or limiting points for the bright beam of liglrt.

lln order that the directlon of this bright beam may be varied, means are provided whereby the casing 15 may be rocked'in: wardly and outwardly in the rim 16. For this purpose a flanged rim 19 is secured to said rim 16* outside the casing 15 and has 1 extending through the upper portion thereof a'pin 20 on which a cylinder 21 having an eccentrically mounted pin 22 thereinis non-rotatably mounted, The pin22 inthe cylinder 21 extends throu h a slot, 23 in an inwardly extending brac et 24 and since said bracket is secured to the upper portion of the casing 15, rotation of the pin 20 acts to move the pin 22 in the slot 23 and rocks the casing 15 inwardly or outwardly in the rim 19 and changes the position of the incense.

mans limiting the bright beam. This 3,?- rangement of course enables the operator I of the headlight to change the angle of downward direction of the main beam of light.- I

While practical embodiments of my'invention have been shown and described herein, it is not purp'osed to limit the same to the specific construction set forth, the novel idea of the invention being to provide a headlight converter wherein separated .means extending transyersely of the head;

1. in a headlight comprising a casing,

a source of light, a reflector and a transparent closure, means between the reflector and closure comprising an extension on one of them for establishing a boundary to the bright portion of the beam of light and to cause the bright beam of light to issue below the axis of the headlight, said means including a non-transparent portion extending from said beam upwardly and-another nontransparent portion extending from said beam downwardly,- the edges\of said per tions being approximately in the same horizontal plane.

2. In a headlight comprising a casing, a source or ii ht, a reflector and a transparent closure, a unnel-shaped translucent casing rojecting rearwardly and integral with the ower half of the closure, an inclined condensing lens at the innero ening of the funnel-shaped casing and in rent of the reflector to cause the deflection of the bright beam downwardly below the horizontal axis of the headlight, said funnel-shaped casing serving as a boundary to the bright portion of the beam.
